本文介绍了TypeError:无法读取未定义的属性';byteLength';-AWS S3上载的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在从Reaction客户端上传AWS S3照片,遇到以下错误:
TypeError: Cannot read property 'byteLength' of undefined
我假设Upload对象中有缺陷,但我认为S3/Cogito配置可能有问题,因为我在调用s3.listObjects
时收到了相同的错误。我正在关注这些文档-https://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/s3-example-photo-album-full.html
有什么想法吗?
uploadPhoto() {
const files = document.getElementById("photoUpload").files;
if (!files.length) {
return alert("Please choose a file to upload first.");
}
const file = files[0];
const fileName = file.name;
const albumPhotosKey = encodeURIComponent('screenshots') + "/";
const photoKey = albumPhotosKey + fileName;
// Use S3 ManagedUpload class as it supports multipart uploads
const upload = new AWS.S3.ManagedUpload({
params: {
Bucket: <Bucket Name>,
Key: fileName,
Body: file
}
});
const promise = upload.promise();
promise.then(
function(data) {
alert("Successfully uploaded photo.");
console.log('UPLOAD: ', data)
},
function(err) {
console.log('ERROR: ', err)
// return alert("There was an error uploading your photo: ", err.message);
}
);
}
推荐答案
我在Reaction本机应用程序中遇到此错误。我可以通过关闭开发工具网络检查器来修复它。
